Grid-tied solar systems are not a common dinner-table topic but it has caught my attention after reading some fascinating material about the concept, installation, costs and end results. At home, our typical consumption is anywhere between .3 to .8 kw according to our energy meter. Of course, things like our dryer drive that up when we cannot use the clothesline.
Doing some searching, I found that I can pickup a 250 watt solar panel for under $300
Quite a deal, but 250 watts wasn't going to make it worthwhile, but perhaps 4 of these would, if not more, generating a peak of 1000 watts, or an average of 34 amps, it would easily drive a grid tied inverter of at least 300 watts or more. Take a look at this or similar on Amazon.

Will this sort of technology run a whole home? While its possible, its not feasible because you would need the storage component, being batteries. Expensive, heavy and takes up real estate. The grid-tie merely supplements the hydro utility, reducing the draw from them. That means our typical standby can be reduced (or possibly) eliminated. At least while the cells are exposed to sun. High draw items will still need the utility system.
Is it worth it? I'm still working on the math and logistics, but it seems promising. Stay tuned.
